S-GH, VertiPlate™ Inorganic Hard-layer TLC plates contain a special inorganic binder plus gypsum that stabilizes the layer to make it more abrasion resistant. They provide improved handling and sample application compared to Soft-layer plates and are tough enough to write on with a soft pencil, if required. They are also 100% water resistant and are compatible with aqueous developing solvent. They are recommended for all applications including those where visualization occurs through strong charring procedures or in any case in which reagent interaction with an organic binder occurs.

     PS, Prescored plates are an economical alternative to having many different size plates. Prescored 20x20cm plate has 3 score markes 5cm apart. Plates can be easily snapped apart to provide four 5x20cm plates. Prescored 10x20cm plate provides four 2.5x10cm plates. PC, Prechanneled plates help prevent cross contamination by separating multiple samples. More sample can be separated on a plate and the spot zones can be determined more readility. Prechanneled 20x20cm plates have 19 channels. Prechanneled 10x20cm plates have 9 channels. Prechanneled 5x20cm plates have 4 channels.

     PA, Preadsorbent plates have a nonadsorbent layer at the bottom of the plate. This band of innert material reshapes and concentrates the spots into narrow bands which improve separation. It allows the loading of large volumes of sample without loss of resolution
